Those they DO sell ;-)

Hehe... just as long as you don't hear a "poof!" and see black smoke.
Then you know months/years of work has gone to waste :-(

I've mailed the list-owner about it, still waiting for a reply.

Something I would like to try out some day as I've used UNIX a lot before.

Oh well.... we're not living in a perfect world ;-)

So everything else is ready?
How about the 19" rack? Have you made that ready as well?
Not me. As mentioned earlier in this thread I'm intending to
incorporate an effects unit as well, so there will be some redesigning
of the front panel.
That'll be the "fun" part, though it'll be a lot of patience work to
make the square holes etc.

Anyway.... I've spent even more time on the "drawing board" again. This
time redrawing the modifications in a way which I hope should be very
clear and easy to understand.
Can you verify if it's correct? Just to be 100% sure I mean.

Then there are the jack sockets. I can probably figure it out myself,
but instead of using even more time and aggrevation on this, and
possibly misunderstand again, can you take a look and perhaps fill in
what's "1a", "1b" and "2a", "2b" of each socket (SK1 and SK2)?

I've simply written "1?" and "2?" there for now as I'm pretty sure I've
at least got the right place for the connections (pink).
Also, for SK1, there's one connection point missing. I suppose this is
something like for RV1, when the brain-dead design hasn't made a hole
in the PCB for it.
Should it be connected to ground as well?

Maybe you can check it with your working circuit so we can get this 100% right?

The new diagrams are available at:

(this is NOT the same URL as the previous one -just thought I'd leave
it there if we should need the old one as well).
